Fuel cells convert chemical energy directly into electricity in a clean and silent electrochemical process, but face challenges related to hydrogen storage, handling, and transportation. The direct borohydride fuel cell (DBFC), utilizing sodium borohydride as a liquid fuel, is a promising alternative to overcome such issues but requires the design of cost-effective nanostructured electrocatalysts. In this study, we synthesized nitrogen-doped graphene anchoring Ni nanoparticles (Ni@NG) by thermal degradation of polyethylene terephthalate bottle waste with urea and metallic Ni, and evaluated it as a sustainable carbon support. Electrocatalysts were prepared by incorporating ultralow amounts (0.09 to 0.27 wt.%) of Pd into the Ni@NG support. The resulting PdNi@NG electrocatalysts were characterized using ICP-OES, XPS, TEM, N2-sorption analysis, XRD, and Raman and FTIR spectroscopy. Voltammetry assessed the materials\u2019 electrocatalytic activity for oxygen reduction and borohydride oxidation reactions in alkaline media, corresponding to the anodic and cathodic reactions in DBFCs. The electrocatalyst with 0.27 wt.% Pd loading (PdNi_15@NG) exhibited the best performance for both reactions. Consequently, it was employed as an anodic and cathodic material in a lab-scale DBFC, achieving a specific power of 3.46 kW gPd\u22121.<\/jats:p>","DOI":"10.3390\/su16177469","type":"journal-article","created":{"date-parts":[[2024,8,29]],"date-time":"2024-08-29T11:12:13Z","timestamp":1724929933000},"page":"7469","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Effective Fuel Cell Electrocatalyst with Ultralow Pd Loading on Ni-N-Doped Graphene from Upcycled Water Bottle Waste"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7594-0289","authenticated-orcid":false,"given":"Aldona","family":"Bal\u010di\u016bnait\u0117","sequence":"first","affiliation":[{"name":"Department of Catalysis, Center for Physical Sciences and Technology, 10257 Vilnius, Lithuania"}]},{"given":"Noha A.","family":"Elessawy","sequence":"additional","affiliation":[{"name":"Computer Based Engineering Applications Department, Informatics Research Institute IRI, City of Scientific Research & Technological Applications (SRTA-City), Alexandria 21934, Egypt"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0203-4012","authenticated-orcid":false,"given":"Biljana","family":"\u0160ljuki\u0107","sequence":"additional","affiliation":[{"name":"Center of Physics and Engineering of Advanced Materials, Laboratory for Physics of Materials and Emerging Technologies, Chemical Engineering Department, Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1423-1147","authenticated-orcid":false,"given":"Arafat","family":"Toghan","sequence":"additional","affiliation":[{"name":"Chemistry Department, College of Science, Imam Mohammad Ibn Saud Islamic University (IMSIU), Riyadh 11623, Saudi Arabia"},{"name":"Chemistry Department, Faculty of Science, South Valley University, Qena 83523, Egypt"}]},{"given":"Sami A.","family":"Al-Hussain","sequence":"additional","affiliation":[{"name":"Chemistry Department, College of Science, Imam Mohammad Ibn Saud Islamic University (IMSIU), Riyadh 11623, Saudi Arabia"}]},{"given":"Marwa H.","family":"Gouda","sequence":"additional","affiliation":[{"name":"Polymer Materials Research Department, Advanced Technology and New Materials Research Institute (ATNMRI), City of Scientific Research & Technological Applications (SRTA-City), Alexandria 21934, Egypt"}]},{"given":"M.
